Little Green Button will not notify user of an emergency if it shares a location name with the creator of the emergency. This is by design to ensure that users can request assistance discreetly without an assailant being made aware that a panic alarm has been triggered.
In other words if you have 3 buttons all configured with the location name ‘Reception’, if the panic alarm is triggered on any of these PCs the alerts will not be displayed on the other 2 PCs.
This is also the case for any optional hardware you may have connected to a PC, if it shares the same location name as the desktop button an alert will not be displayed on the PC that the hardware is connected to. If it is configured with a different location name, for example, if the hardware is installed in the room next door an alert will be displayed on the PC if the switch/strip is activated.
